| Zusammenfassung |
| The Double Star Project is a collaboration between Chinese and European
space agencies, in which two Chinese magnetospheric research spacecraft,
carrying Chinese and European instruments, have been launched into
equatorial (on 29 December 2003) and polar (on 25 July 2004)
orbits designed to enable complementary studies with the Cluster spacecraft.
The two Double Star spacecraft TC-1 and TC-2 each carry a Double Star Plasma
Electron and Current Experiment (PEACE) instrument. These two instruments
were based on Cluster Flight Spare equipment, but differ from Cluster
instruments in two important respects. Firstly, a Double Star PEACE
instrument has only a single sensor, which must be operated in a manner not
originally envisaged in the Cluster context in order to sample the full
range of energies. Secondly, the DPU hardware was modified and major changes
of onboard software were implemented, most notably a completely different
approach to data compression has been adopted for Double Star, which allows
high resolution 3-dimensional distributions to be transmitted almost every
spin, a significant improvement over Cluster. This paper describes these
instruments, and includes examples of data collected in various
magnetospheric regions encountered by the spacecraft which have been chosen
to illustrate the power of combined Double Star and Cluster measurements. |
